Title: Method for producing pig iron
Inventor: VULETIC BOGDAN
IPC: C21B13/14
Filed: 2000-11-28
Granted: 2004-02-05
Abstract: The invention relates to a method for producing pig iron. Iron ore is reduced in a reduction shaft (1) for forming sponge iron which is subsequently introduced into the head of a melt-down gasifier (3). The sponge iron is melt open in said gasifier by means of a gasifying means that is also introduced into the head of the melt-down gasifier and an oxygen-containing gas and is melt-down to form liquid pig iron, whereby a reduction gas is produced at the same time. Said reduction gas is discharged from the head of the melt-down gasifier and is supplied to the reduction shaft for reducing the iron oxide. Operation of the melt-down gasifier is controlled in such a way that a reduction gas having a certain composition and being present in a certain amount is produced so that the sponge iron that is introduced into the melt-down gasifier is provided with a high metallisation degree. Operation of the melt-down gasifier is also controlled by introducing iron oxide therein. The metallisation degree of all the iron carriers which are introduced into the melt-down gasifier is reduced in relation to the metallisation degree of the sponge iron and by means of said iron oxide.

Title: Curb-inlet storm drain systems for filtering trash and hydrocarbons
Inventor: MORRIS JAMES F
IPC: C02F1/68
Filed: 1999-02-17
Granted: 2002-09-05
Abstract: A modular insert for curb-inlet storm drains creates a composite collection system for trash and for oil or other hydrocarbons and related chemicals. A hopper contains a multitude of irregular, macroscopic fragments of a hydrophobic, compliant, oil-absorbent, copolymer material having high surface area. Preferably, the material is formed with a binder in a novel extrusion process. The fragments absorb and retain permanently a high quantity of oil and other chemicals passing through the hopper, while permitting a high water flow-through rate. The fragments are held in place by a removable bottom plate, which allows replacement of the filtering fragments, and an internal basket. Trash and debris are collected in the internal basket. The hopper is configured to be suspended in a storm drain adjacent to a curb inlet on a bracket and can be installed or serviced through a conventional manhole entry. The hopper has a side cutout that permit lateral overflow from one of the modular units to an adjacent one.

Filed: 1997-08-29
Granted: 1999-12-23
Abstract: A method and apparatus for the construction of a two-layer flooring system for use at a construction site such as an oil well drilling site. The flooring system is particularly well suited for use in areas with dry, sandy soil. The flooring system is formed by interlocking both the ends and sides of a plurality of mat units. Each of the mat units includes two layers of boards. The first layer has end locking tabs extending beyond the edge of the first layer and corresponding end locking slots, formed by offsetting selected boards. The second layer similarly includes side locking tabs and corresponding side locking slots, also formed by offsetting selected boards. The arrangements of these tabs and slots is such that half-size units and inverted units may be utilized, allowing a wide variety of patterns of interlocking units to be utilized for the flooring system. The method of constructing a flooring system utilizing such units includes positioning one mat unit adjacent to other mat units and inserting the tabs into the corresponding slots to interlock the units. By interlocking a plurality of such units, a two-layer flooring system is fabricated at a construction site which is strong and sturdy enough to support heavy equipment, yet easily installed and removed.
